CUTTING-MACHINE.

To all whom it may concern.

Be it known that I, LEO HIRSCHFELD, a citizen of the United States, anda resident of the city, county, and State of New York, have inventedcertain Improvements in Cutting-Machines, of which the following is aspecification.

This invention relates to certain improvements in cutting machines, andmore particularly in that class of such machines which are especiallydesigned and adapted for employment in cutting or severing elongatedrods or strips into shorter lengths or sections, and the object of theinvention is to provide a machine of this general character of a simpleand comparatively inexpensive nature and of a strong and compactconstruction, which shall permit of convenient and effective use forsevering such rods or strips into desirable lengths with great rapidityand without requiring any special skill or attention upon the part ofthe attendant.

The invention consists in certain novel features of the construction,and combinations and arrangements of the several parts of the improvedcut-ting machine, whereby certain important advantages are attained, andthe device is rendered simpler, less expensive, and otherwise betteradapted and more convenient for use, all as will be hereinafter fullyset forth.

The novel features of the invention will be carefully defined in theclaims.

In order that my invention may be the better understood, I will nowproceed to describe the same with reference to the accompanyingdrawings, wherein Figure l is a side elevation showing a cutting machineembodying my invention, the same being constructed in a formparticularly adapted for use in severing long sticks or rods of candyinto short lengths or sections; Fig. 2 is a plan view of the machineconstructed as shown in Fig. 1; Fig. 3 is an enlarged sectional viewtaken vertically through the cutting devices of the machine in the planeindicated by line c&a, in Fig. 2; Fig. 4 is a view similar to Fig. 3,but showing the operation of the guiding means in preventing clogging ofthe machine, and Fig. 5 is a fragmentary sectional view showing afeature of construction to be hereinafter referred to.

As shown in these views the cutting ma- Specification of Letters Patent.

chine embodying my invention is mounted upon a rectangular frame ortable 1, having a central space or opening, and supported upon legs 2,at a convenient height above the floor, there being alined hearingpieces 3, 3 erected at opposite sides of one end of said frame or table,in which bearing pieces is held a transversely extended shaft 4, one endof which carries, outside said frame or table, a pulley-5, over which ispassed a belt or band 6, by means of which rotatory movement may beimparted to said shaft from any convenient source of power for theoperation of the improved cutting ma.- chine.

7 represents a cutting drum or cylinder, which is held upon the shaft 4between the sides of the frame or table 1 in such a manner as to turn inunison with said shaft, and this drum or cylinder 7 carries a plurality:of circular or disk like cutters 8, 8, which may be conveniently formedfrom thin sheet or plate metal of such diameters that their perimetralportions are caused to project in annular form around the perimetralsurface of said drum or cylinder. The said drum or cylinder 7 may, ifdesired, be produced from a plurality of sections 9, 9 alined end toend, and adapted to receive the cutting disks 8, 8 between them in sucha manner as to operate to hold said disks spaced apart upon the shaft 4at such distances as may be proper according to the lengths or sectionswhich are to be cut. Vhen the machine is constructed as herein shown,particularly for cutting or severing candy rods or sticks, theperipheral edges of the cutting disks 8, 8 need not be sharpened, butwill preferably be made smooth and blunt.

The projecting parts of the cutting disks- 8, 8 at one side of the drumor cylinder 4 play through slotted apertures 10, 10 produced in theadjacent edge portion of a guide plate 11, which is extendedtransversely across the central opening of the frame or table 1 parallelwith the shaft 4, and is supported at its lower edge portion by atransverse brace 12, being thence eX- tended in an upwardly inclineddirection toward said drum or cylinder 7, and having its upper edgeportion divided by the slotted openings 10, 10 into spaced inclinedguide tongues 14, 14 which are extended between the cutting disks 8, 8and have engagement at their free edges upon the peripheral parts" ofsaid drum or cylinder 7 which intervenes between said cutting disks 8,8, as clearly shown in Figs. 3 and 4 of the drawings.

At the side of the frame or table opposite to the pulley 5, the shaft 4which carries the drum or cylinder 7, is provided with a sprocket wheel15, over which is passed a chain or link belt 16, extended thence arounda similar sprocket wheel 17 upon the adjacent end of a shaft 18 which isextended across the frame or table parallel with the shaft a and at theside of drum or cylinder 7 opposite to the guide plate 11, and isjournaled in the bearing pieces 3, 3 at opposite sides of the table orframe 1, the construction and arrangement of the parts herein shownbeing such that said shaft 18 is continuously driven in unison with themovement of shaft 1, but in a direction reverse to that in which saidshaft at is driven.

The shaft 18 carries, at its central part and opposite the centralopening of the frame or table, a drum or cylindrical feed member 19,which is secured to turn with said shaft and has its perimetral surfacearranged to move in close proximity to the peripheral edge portions ofthe cutting disks 8, 8 upon the drum or cylinder 7, but preferably outof contact therewith, and said perimetral surface of said cylindricalfeed member 19 is herein shown as provided. with longitudinally extendedgrooves or kerfs 20, 20, spaced apart in such a way as to impart to saidsurface of said feed member a fluted or roughened formation such as isparticularly well adapted to insure such engagement upon the candy rodor stick, indicated at 00, when the same is placed in the bight of saidmember 19 with the cutting disks 8, 8, as shown in Fig. 3 of thedrawings, as is needful to imparta certain rotatory or rolling movementto said rod or stick where by the cutting disks are caused to operateevenly around the entire circumference of said rod or stick, to severthe same into the desired lengths without liability of splintering orcracking of the candy, or clogging of the machine due to adhesion of thecandy to the operative parts.

21 represents an auxiliary feed roll or member having a lesser diameterthan the feed member 19, and also grooved or fluted upon its peripheralsurface as shown at 22, and said auxiliary feed member is extendedacross the frame or table 1 parallel with the shafts a and 18, and hasits extremities provided with conical parts 23 which are supported inbearing pieces 24, carried by the arms 26, 2(5 of a yoke, comprising ahandle bar 27 joining the upper ends of said arms 26 and adapted to begrasped by the hand of the attendant, as will be hereinafter explained,and a brace bar 28 extended between said arms 26 above said auxiliaryfeed roll or member 21, the lower ends of said yoke arms 26 beingpivoted as shown at 29 upon brackets 30, 30 secured at opposite sides ofthe frame or table 1, and the parts being so proportioned and arrangedthat when said yoke is grasped by the handle bar 27 and pivotally moveddownward, as shown in dotted lines in Fig. 3, said auxiliary feed rollor member 21 is caused to contact upon the candy rod or stick as, restedin the bight of the member 19 and disks 8, 8, with such moderate andgraduated pressure as is desirable to hold the candy in accurate contactwith said disks 8, 8 during cutting thereof. The auxiliary feed member21 being mounted for turning movement in its bearings, and being fittedupon its perimeter, is capable of being driven from contact of the candyrod or stick a; therewith, so that flattening of the candy, interferencewith the rolling movement thereof, and clogging of the machine areeffectively avoided. One of the bearing pieces 24 has screw adjustmentin the corresponding yoke arm 26, as shown in Fig. 5, so that wear maybe taken up when necessary, and said adjustable bearing piece has a locknut 25 for holding it in adjusted position.

In the use of the machine constructed as above described, the candy willusually be supplied in the form of elongated rods or sticks ofcylindrical cross section, and then are successively inserted at thebight of the member 19 with the cutting disks 8, 8, the engagement ofsuch parts being such as to operate, in connection with their reverserotatory movement, to impart a rolling movement to the candy, wherebythe edge portions of the cutting disks are caused to contact with thecandy rod or stick around its entire peripheral surface. After theinsertion of each rod or stick at in the bight of member 19 and disks 8,8, the operator grasping the handle bar 27 of the pivoted yoke, which isnormally elevated, as shown in full lines in Fig. 3 to permit theconvenient introduction of the candy, will draw said yoke downward witha graduated pressure, whereby the auxiliary feed roll or member 21 iscaused to press upon the candy rod or stick so as to force the samedownward to the position shown in dotted lines in Fig. 3, withoutinterfering with the rolling movement of said candy. In this way, thecutting disks 8, 8 are caused to sink into the candy rod or stick atproper intervals along the length thereof, and the rolling movement ofthe candy will insure that the cuts produced by said disks 8, 8 will beextended uniformly around the rod or stick 00 so that splintering ordeformation of the candy is prevented, and the same is evenly and neatlysevered into lengths or sections of the size desired. The candy beingsevered or cut into the desired lengths, will lodge between the disks 8,8 and by the upward movement of the said disks, as indi cated by thearrow in Fig. 3, will be moved toward the perimeter of the drum orcylinder 7 so as to pass .from beneath the auxiliary feed roll or member21, and by the continued movement of said disks 8, 8 the lengths orsections of candy will be presented as shown in Fig. a upon the inclinedupper surfaces of the guide tongues ll, 14 which will operate towithdraw said lengths or sections from between said disks 8, 8 withoutcracking or flattening of the candy, after which the lengths or sectionswill roll freely down the inclined guide plate 11, and fall into areceptacle 31 suitably arranged to receive them.

From the above description it will be evident that the machine embodyingmy improvements is of an extremely simple and comparatively inexpensivenature, and is particularly well adapted for use by reason of thefacility and rapidity with which candy and similar substances may besevered or cut into desired lengths or sections, and of the assuranceagainst breakage or deformation of the severed lengths afforded by it,and it will also be obvious from the above description that the machineis susceptible of considerable modification without material departurefrom the principles and spirit of my invention, and for this reason I donot desire to be understood-as limiting myself to the precise formationand arrangement of the several parts herein set forth in carrying out myinvention in practice.
